Be it known that we, ALBERT P. SEYM0Un,J1-., of Hecla Works, in thecounty'of Oneida, and State of New York, and W. RILEY Goonmcn, ofWhitestown, in the same-county of Oneida, and- Stateof New York, haveinvented a new aud useful Improvement in Axle-Pulleys for Window-Sashes,and other purposes,- of which the following isa full, clear, and exactdescriptiomteference being had to the accompanyingd'rawing, forming partof this specification, and in which- Figure 1 represents a side view ofan axle-pulley frame, shell, or box, with pulley arranged therein.Figure 2atransverse section of the samefdnd v Figure 3 a similarsection, but she wing the pulley removed. s Figure 4shows a face view,with pulley removed, illustrating a modification of the sameconstruction, and Figure 5 a transverse section, taken as indicated bythe line a: a: in fig. 4. imilar letters of reference indicatecorresponding ports.

Axle-pulleys, as ordinarily constructed, that is, such as are used forwindow-sashes, have the checks of their frame, shell, or box, unitedtogether and to the face-plate of the frame by rivets, passed thronghthe outer 1 ends of the cheeks, and through songs or projections, caston the back of thc-facc-plnte. This is both a. troublesome and expensivemode of fastening, involving, as it does, the dflicult process ofdrilling small holes through parts of castings, generally or necessarilyhard, and a'lso involving troublesome or expensive riveting.Our-invention consists in so constructing the pulleysthut the face-platemay-be locked to the cheek-plates without the use of rivets, as abovedescribed, a single intermediately-arrenged rivet being used at the backof the cheek-plates, which will be founda much more economical andfirmer construction of axle-pulleys.

The cheek-plates and face-plates maybe locked'toge'ther, as abovereferred to, in various ways, two of ;W-hi0ll' we have shown in theaccompanying drawings, and hereinafter described.

Qur invention, as above referred to, may be applied to the ordinary modeof. constructing the bearings or pivots of the pulley, the pivets beingcast on the pulley, and allowed to turn in the holes made through thecheeks of the frame. In order, however, te-s'ccure a cheaper plcn ofconstruction, our invention consists, further, in casting thepulley-proper with a. hollow bush or bearing, and the cheek or checksof'thc' frame with the pivot or-pivots for the pulley to turn on, whichcheaper plan may be used, if desired, in place of the ordinary methodabove mentioned or described.

Referring, in the'first instance, to figs. 1, 2, and-3, of theaccompanying drawing, A represents the faceplate of the frame, and a theopening in or through it for projection of the pulley Said face-platehas cast enits back, at either end of the opening a, n hook-shapedprojection, b, and side tips or flanges, a, between which latter and thesides of the hooked projections 6, the outer ends of the cheeks B B areslid -or entered,

' and made to gear with the projections b by snugs or ears 02, arrangedto bite or lap underthe hooked ends of the projections 6, after which(the pulley being in its place) a single intermediate rivet, e, passingthrough flangeprojections, f," at the back, will' serve, in conjunctionwith the locking-arrangement at the outer end of the cheeks, asdescribed, to make a firm, close, and expeditious mode of holding thecheeks and face-plate together. I In figs. 4 and 5, virtually thesamearrangement of construction for the frame is shown,'but, in thismedification, the lock- 0'! gear of the cheeks with the'fuce-plzite A isestablished by forming the hook or dovetail shaped projections b-on theouter ends of the cheeks, and projecting them through the opening a inthe face plate, so as to lock with the latjenover the edges 8 of theopening a. I

The pulley G shown in figs. 1 and 2 of the drawing, is formed with abush or socket-bearing, g, throughit, and the cheeks, either one or bothof them, have cast to them, on their inner fuce, the pivot or pivots It,

thus strengthening the cheeks, and giving a close construction to theframe.

What is here claimed, and desired to be secured by Letters Patent,isi 1. The construction of the cheeks B B with projections, locking in adove-tailed or hooked manner, within or through the face-plate A, andsecured by a'rivet, e, helding the said cheeks together by the lugs orears f, at their outer edge, substantially as shown and described.

2. Farming thev pivot or pivots, on which the pulley 0 turns, by aprojectien or projections, b, cast onor to the inside of the cheek orcheeks B of the frame, substantially as described.
